Hi.
I’d like to build my own bt boombox I don’t have that many parts for it atm but the plan is.
have either 4s or 5s 18650 not sure if I need a 1p,2p,3p and so on with a BMS and I’d like to be able to charge it with either 220VAC or 19~DC laptop psu I have a lot of dell/sony once they are about 19.5V 4.7A.
just say I get 4x3” full range 8ohm 2 on each side and add a passive radiator to that.
or will it be better to get 2x2-3” full range and 2x3-4” midd/sub with a passive radiator.
im not sure on the parts I’ll get it will be most likely cheap stuff like from AliExpress at least the bt board and amplifier boards.
i think it can be hard if i get the speakers from AliExpress to you don’t have all the t/s so how to calculate the box and passive radiator isn’t that easy “not for me anyway”
not sure on what I’d search for too find the info I need so if anyone can point me in a good direction I’d appreciate it.
Dayton speakers and bt/amp/dsp boards do look very nice but it will cost to much for me.
but any help I can get would be nice
thanks in advance /mattias

Forgot.
the BT decoder board I would like it so to increase / decrease the volume is done by the phone.
i know some have so you can change the volume a little bit with the phone but you can till increase the more on the decoder board.
i have got these parts already only got them to test it a little.
Decoder board with amp on it but I think it has a line out to add another amplifier

Your links are broken Matthias, you might find it easier to use a URL shortener.
Take everything I say with a pinch of salt, I might be wrong and it's a very *expensive* way to learn!

think I’ve fixed it now.
missed that the ”I found*” was added before the link

That's all good now. These share links are a bind aren't they?
